usual manner. Besredka, who first introduced this 

 method in vaccinating against plague, cholera, and 

 enteric fever, claims that with these sensitised vaccines 

 active immunity is produced in the inoculated in- 

 dividual almost immediately. Broughton-Alcock uses 

 sensitised living vaccines of the pyogenic cocci in the 

 treatment of streptococci and staphylococci infections 

 with remarkable success. This method has now been I 

 extended to include the treatment of numerous 

 different bacterial infections in the human subject. 

 It is worthy of trial in veterinary practice, where it is 

 so much easier to obtain a homologous specific serum 

 than in human practice. It should be admirably 

 suited to give active immunity to healthy animals in 

 an outbreak of strangles.
